But if the macroscopic world is a consequence of the microscopic behaviour, how would you know how to simulate the macroscopic without simulating the microscopic?

With the microscopic being unsimulated, would there not be macroscopic effects without any causes? Wouldn't be be able to detect this discrepancy on further investigation?

If you had to retroactively simulate a cause for all effects that get investigated, wouldn't it be simpler to just simulate the microscopic in the first place?
